ec@shyychina.comOur roller sleeves use high-chromium cast iron alloyed with molybdenum, copper, manganese, and other elements. This optimized alloy system improves hardness, toughness, and resistance to abrasive wear.
Advanced casting technology combined with a tire-shaped profile enhances grinding efficiency and load distribution. The optimized structure helps minimize common wear issues such as peeling, chipping, and surface cracking during continuous operation.
Yingyong supplies customized roller sleeves for vertical roller mills based on customer drawings or technical specifications. Each solution matches specific operating conditions, material characteristics, and load requirements.

Performance in Vertical Roller Mills
Roller sleeves operate under high pressure and abrasive conditions. Material stability and structural integrity are therefore critical.
In cement and mining applications, our roller sleeves perform reliably under continuous high-load grinding conditions. They maintain stable wear patterns and consistent grinding performance, even when handling abrasive materials such as limestone, slag, quartzite, and gypsum.
